A cell loss priority control method for an ATM switch in which degradation of the traffic characteristics of a high priority class or a low priority class is detected, a cell loss probability distribution in a buffer is estimated from the cell traffic characteristics, a buffer threshold value is obtained in accordance with the estimated cell loss probability distribution, and the cell is controlled by using the obtained buffer threshold value which maximizes total traffic throughput of both the high priority class and low priority class.
